<Configuration example of linked staples>
The connected staple 1 is formed by connecting staples 2 and is used by being loaded on a stapler 3 described later. The stapler 3 separates the staple 2 located at the end of the connected staple 1. The separated staples are formed in a substantially U shape by the stapler 3 and then penetrated into the binding paper, and both the leg portions penetrated are folded and bonded to each other. In this way, the binding sheets are bound.

  1 and 2 are explanatory views showing the configuration of the staple 2a of the first example and the connected staple 1a of the first example in which the staple 2a is connected. Fig.1 (a) is a top view which shows the detail of the connection staple 1a. FIG. 1B is a perspective view showing a state in which the staple 2a is formed in a substantially U shape. FIG. 2 is an explanatory view showing a state in which the connected staple 1a is attached to the release paper 30 and wound as a roll staple 4 in a roll shape. The connected staple 1a, the staple 2a, and the roll-shaped staple 4 are configured as follows, for example.

  As shown in FIG. 1 (a), a plurality of staples 2a having an elongated and substantially straight shape are arranged in parallel in the longitudinal direction and connected to each other to form a connected staple 1a. Each of the staples 2a has, for example, a width of about 5 to 10 mm in the vertical direction (the connecting direction of the staples 2a) in FIG. 1A, and a width in the horizontal direction (the longitudinal direction of the staples 2a) in FIG. It is about 30 to 40 mm. The vicinity of the end in the longitudinal direction of each staple 2a is formed in a substantially trapezoidal shape, and the width gradually decreases toward the tip. Moreover, the back surface (surface to which the release paper 30 is attached) in the vicinity of both end portions in the longitudinal direction of each staple 2a is provided with adhesive portions 31 (31a, 31b) to which an adhesive is applied.

  In addition, elliptical feed holes 32 are provided at predetermined positions from both ends of the sides to which the staples 2a are connected. A slit portion 33 is provided between the two feeding holes 32, and each staple 2a is completely separated. Out of the two feed holes 32, the staples 2a are connected as staple connecting portions 34 up to both ends of the side where the staples 2a are connected.

  Further, the staple 2 separates the staple 2 at the end from the connected staple 1a shown in FIG. 1 (a), and the leg portions substantially perpendicular to the crown 35 and the crown 35 as shown in FIG. 1 (b). 36 is formed into a substantially U-shaped bent shape.

  FIG. 3 is a cross-sectional view showing a state in which the binding sheets 37 are bound by the staple 2a. As shown in FIG. 3, the staple 2a formed in a substantially U-shape is passed through the binding paper 37, and then both legs 36 are bent along the binding paper 37 to bind the binding paper as a binding paper bonding portion. 37 and an adhesive portion 31a (shown by A in FIG. 3) of one leg portion 36, and one leg portion 36 as an adhesive portion of both legs and an adhesive portion 31b of the other leg portion 36 (shown by B in FIG. 3). ) Are pasted together. Accordingly, it is possible to improve the holding property of the binding paper 7 by the staple 2a in a state where the binding paper 37 is bound by the staple 2a. Further, in the staple 2a, when the binding paper 37 is bound, there is no gap between the binding paper 37 and the staple 2a, and it is possible to improve the appearance of the staple 2a in the bound state.

  Further, as shown in FIG. 2A, the linked staple 1a is attached and wound around a release paper 30 as a first release paper and a second release paper in a stored state. The release paper 30 has a function as a first release paper and a function as a second release paper. As shown in FIG. 2B, a predetermined length of release paper 30 is peeled off from the leading end of the linked staple 1 a and loaded into the stapler 3. A detailed method of loading the stapler 3 will be described later.

  In the connected staple 1a according to the present invention, the release paper 30 is attached to the adhesive portions 31 (31a, 31b) on the back surface of each staple 2a, and the adhesive portions 31a, 31b are protected. For this reason, it becomes possible to prevent the adhesiveness of the adhesion part 31b for bonding both the leg parts 36 together and the adhesion part 31a between the binding paper 7 and the both leg parts 36 from being deteriorated.

  Next, the staple 2b and the linked staple 1b of the second example will be described. FIG. 4 is an explanatory diagram showing the configuration of the staple 2b of the second example and the connected staple 1b of the second example in which the staple 2b is connected. FIG. 4A is a plan view showing details of the linked staple 1b. FIG. 4B is a perspective view showing a state in which the staple 2b is formed in a substantially U shape.

  The staple 2b is different from the staple 2a described in FIG. 1 only in the position of the feed hole 32. The staple 2b includes a circular feed hole 32 at the center of each staple 2b. Similar to the staple 2a, the staple 2b includes an adhesive portion 31 (31a, 31b), a slit portion 33, and a staple connecting portion 34.

  Such staples 2b are connected to form a connected staple 1b. The connected staple 1b is in a state where the release paper 30 is attached and the rolled staple 4 is wound, as in the connected staple 1a shown in FIG.

  Next, the staple 2c of the third example will be described. FIGS. 5A to 5C are explanatory views of the staple 2c of the third example. The staple 2c is different from the staple 1a shown in FIG. 1 only in the configuration of the bonding portions 31a and 31b. In the third staple 2c, the adhesive portion 31a bonded to the binding paper 37 shown in FIG. 3A is weaker than the adhesive portion 31b attached to the other leg portion 36 shown in FIG. 3B. To demonstrate.

  The staple 2ca shown in FIG. 5A has an adhesive portion 31a having a smaller area than the adhesive portion 31b. As a result, the bonding portion 31a bonded to the binding sheet 37 exhibits a weaker adhesive force than the bonding portion 31b bonded to the other leg portion 36.

  The staple 2cb shown in FIG. 5B has an adhesive portion 31a to which an adhesive having a weak adhesive strength is applied as compared with the adhesive portion 31b. As a result, the bonding portion 31a bonded to the binding sheet 37 exhibits a weaker adhesive force than the bonding portion 31b bonded to the other leg portion 36.

  The staple 2cc shown in FIG. 5C is applied with an adhesive having a weaker adhesive strength than the adhesive portion 31b and has an adhesive portion 31a having a narrow area. As a result, the bonding portion 31a bonded to the binding sheet 37 exhibits a weaker adhesive force than the bonding portion 31b bonded to the other leg portion 36.

  In the staple 2c of the third example, the adhesive portion 31a bonded to the binding paper 37 exhibits a weaker adhesive force than the adhesive portion 31b bonded to the other leg portion 36. The legs 36 are bonded with a weak adhesive force. Thereby, when it becomes necessary to remove the staple 2c after binding the binding sheet 37, the removal operation of the staple 2c can be easily performed.

  The staple 2c is connected as a connected staple 1 similarly to the staple 2a shown in FIG. The connected staples to which the staples 2 c are connected are in a state where the release paper 30 is attached and the rolled staples 4 are wound, similarly to the connected staple 1 a shown in FIG. 2.

  Next, the staple 2d of the fourth example will be described. FIG. 6 is an explanatory diagram of the staple 2d of the fourth example. Unlike the staple 2a shown in FIG. 1, the staple 2d of the fourth example includes only the adhesive portion 31b without the adhesive portion 31a. FIG. 7 is a cross-sectional view showing a state in which the binding paper 37 is bound by the staple 2d of the fourth example.

  As shown in FIG. 7, in a state where the binding sheet 37 is bound by the staple 2d, only the both leg portions 36 are bonded together by the adhesive portion 31b, and the binding sheet 37 and the leg portion 36 are not bonded. Thereby, the staple 2d can more easily perform the operation of removing the staple 2c after binding the binding sheet 37, compared to the third staple 2c shown in FIG.

  The staple 2d is connected as a connected staple 1 similarly to the staple 2a shown in FIG. The connected staples to which the staples 2d are connected are in a state in which the release paper 30 as the first release paper is attached and wound as the roll-like staple 4 in the same manner as the connected staple 1a shown in FIG.

  Next, the staple 2e of the fifth example will be described. FIG. 8 is an explanatory diagram of the staple 2e of the fifth example. FIG. 8A is a plan view of the staple 2e, and FIG. 8B is a perspective view showing a state in which the staple 2e is formed in a substantially U shape. As shown in FIG. 8, unlike the staple 2a shown in FIG. 1, the staple 2e does not include an adhesive portion 31a bonded to the binding paper 37 on the back surface. The staple 2e includes only the adhesive portion 31b on the back surface. Further, the staple 2e includes an adhesive part 31c on the surface of the other end part from the end part including the adhesive part 31b.

  Since the staple 2e has such a configuration, in the state where the binding paper 37 is bound by the staple 2e, only the leg portions 36 are bonded together by the adhesive portion 31b and the adhesive portion 31c as shown in FIG. And the leg part 36 is not bonded together. Thereby, the staple 2d can more easily perform the operation of removing the staple 2c after binding the binding sheet 37, compared to the third staple 2c shown in FIG.

  In the staple 2e, for example, a self-adhesive adhesive is applied to the adhesive portion 31b and the adhesive portion 31c as the first adhesive portion and the second adhesive portion. The self-adhesive adhesive generates an adhesive force only when the same adhesive touches it, and does not generate an adhesive force in other cases. Further, in the staple 2e, for example, each liquid of a two-component mixed adhesive is applied to the bonding portion 31b and the bonding portion 31c. The two-component mixed adhesive generates an adhesive force when two kinds of liquid are mixed, and does not generate an adhesive force in other cases.

  FIG. 9 is an explanatory view showing a roll-shaped staple 4e obtained by winding a connected staple 2e configured by connecting the staple 2e into a roll. As described above, the adhesive portion 31b and the adhesive portion 31c of the staple 2e do not generate an adhesive force in a state where they do not touch each other. For this reason, unlike the connected staple 1 in which the first to fourth staples 2 are connected, there is no need to protect the adhesive portion 31b and the adhesive portion 31c with the release paper 30 in the storage state, and as shown in FIG. The staple 1e can be directly wound to form a rolled staple 4e.

  Next, a configuration example of the linked staple 1f of the sixth example will be described. FIG. 10 is an explanatory diagram showing a configuration example of the linked staple 1f of the sixth example. As shown in FIG. 10, in the linked staple 1 f, the last one staple 2 fa has a different color from the other staples 2. For this reason, the user can recognize that the staple 2 loaded in the stapler 3 is finished after the binding sheet 37 is bound by the last staple 2fa.

  Next, a configuration example of the linked staple 1g of the seventh example will be described. FIG. 11 is an explanatory diagram illustrating a configuration example of the linked staple 1g according to the seventh example. As shown in FIG. 11, the connected staple 1g includes an identification tag 2gaa that can be separated by a perforation from the last staple 2ga. For this reason, the user can recognize that the staple 2 loaded in the stapler 3 is finished after the binding sheet 37 is bound by the last staple 2ga. Further, since the identification tag 2gaa can be separated at the perforation, by separating the identification tag 2gaa after binding the binding paper 37, it becomes the same as the state stapled by the other stapler 2.

  Next, a configuration example of the linked staple 1h of the eighth example will be described. FIG. 12 is an explanatory diagram of a configuration example of the linked staple 1h according to the eighth example. 12A and 12B show a configuration example of the linked staple 1h, and FIG. 12C shows a binding sheet 37 with the staple 2 of the linked staple 1h shown in FIGS. 12A and 12B. It is explanatory drawing which shows the state which bound.

  In the linked staple 1h shown in FIG. 12A, all the staples 2 are provided with serial numbers indicated by D. For this reason, the user can check the remaining amount of staples 2 loaded in the stapler 3 for each binding operation.

  In addition, the linked staple 1h shown in FIG. 12B includes serial numbers indicated by E on the last few staples 2. Therefore, the user can check the remaining amount of staples 2 when the remaining amount of staples 2 loaded in the stapler 3 is reduced.

  Next, a configuration example of the linked staple 1i of the ninth example will be described. FIG. 13 is an explanatory diagram showing a configuration example of the linked staple 1i of the ninth example. As shown in FIG. 13, the linked staple 1 i has a configuration in which the color of the staple 2 changes according to the number of remaining staples 2. In the example illustrated in FIG. 13, the staples 2ia to 2ie have different colors. Although FIG. 13 shows an example in which the color of the entire surface of each staple 2 is different, only a partial color of each staple 2 may be different. As a result, the user can check the remaining amount of staples 2 loaded in the stapler 3 for each binding operation.

  In the linked staples 1 of the sixth to ninth examples, the user can recognize that the staples 2 in the stapler 3 are gone. Accordingly, by performing the binding operation in a state where the staple 2 is not loaded in the stapler 3, it is possible to prevent a cutout hole from being formed in the binding sheet 37 by a punching blade of the stapler 3 described later.

  Next, a configuration example of the cartridge 70 of the present invention for loading the roll-shaped staple 4 onto the staple 3 will be described.
